883-26-100
The Fox Performance Elite Series 2.5 Reservoir Rear Shocks (part number 883-26-100) are engineered specifically for 2017–2026 Ford F-250 and F-350 Super Duty trucks running 4 to 6 inches of rear lift. Sold as a pair.
DSC Adjuster: The 2.5" smooth bore and honed seamless alloy reservoir features a Dual Speed Compression (DSC) adjuster, providing independent low-speed and high-speed compression adjustment to dial in performance for any driving style or terrain.
Design: The aluminum shock body and external reservoir efficiently dissipate heat by increasing oil and nitrogen capacity. The larger, high-flow piston increases bottom-out resistance and damping in any environment.
